Abstract
Description
- The present invention generally relates to fluid filters, and more particularly relates to apparatus and methods for venting air through such fuel filters and/or associated housings such as fuel filters where air can be trapped during the replacement of the filter cartridge and must be vented back to the fuel tank or otherwise to provide for good operation.
- In the fuel systems for vehicles, a pump is provided to move fuel through the system from the fuel tank to the engine. Along that path, a fuel filter comprising a filter element contained in a housing is often provided to filter out contaminants and thereby remove the same from the fuel prior to the fuel reaching the engine. Periodically, these fuel filter elements need to be changed. During initial installation and during periodic filter changes, air can be trapped in the housing and fill part of the volume of the housing. The trapped air can decrease the performance of the filter and fuel flow. As such, it is desirable to remove the trapped air from the housing.
- One known method for doing the same is by means of a vent passage that leads back to the fuel tank. A prior art example employing the same is U.S. Pat. No. 7,157,110 in which the venting is through the core of the filter element. However, this design has a very complex and difficult support core within the filter element and further requires a special one-piece grommet such that off the shelf grommets cannot be readily employed. Thus, improvements over the state of the art are desired.
- One aspect of the present invention is directed toward a filter element comprising top and bottom end caps with the bottom end cap defining a central opening. A tubular ring of filter media extends between the top and bottom end caps. The tubular ring of filter media defines a central open volume. A bleed chamber is defined proximate the bottom end cap. A snorkel is in fluid communication with the bleed chamber and extends along the outside of the filter media with a vent opening closer to the top end cap, than the bottom end cap, which may be used to vent air in a housing when in use.
- Another aspect pertains to this filter element in combination with a housing to provide a filter apparatus. Such apparatus comprises a housing including an inlet and an outlet adapted to filter fuel. A standpipe extends from the base of the housing toward a top of the housing. A fuel path extends from the inlet to the outlet and through the standpipe through the housing. The standpipe includes a first passage along the fuel flow path and a separately defined second bleed passage. The filter element is disposed in the housing and over the standpipe. The filter element comprises a top end cap and a bottom end cap below the top end cap. The bottom end cap defines a central opening receiving the standpipe therethrough. The tubular ring of filter media extends between the top and bottom end caps and also defines a central opening receiving the standpipe. A flow path is provided for fuel flow through the filter media. The bleed chamber is proximate the bottom end cap and in fluid communication with the second bleed passage. The snorkel is in fluid communication with the bleed chamber and extends along the outside of the filter media with the vent opening provided closer to the top end cap than the bottom end cap so that air may bleed through the snorkel, then into the bleed chamber where it may then be received in the bleed passage of the standpipe and housing.
- Another aspect of the present invention is directed toward a method of filtering fuel while venting air through a filter element installed in a housing. The method comprises filtering fluid through the filter media of the filter element; venting air trapped in the housing through a snorkel integrally part of the filter element; and extending the snorkel along the outside periphery of the filter media.
- Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
-
FIG. 1 is a cross-section of a filter apparatus including a housing and a filter element in accordance with an embodiment of the present invention. -
FIG. 2 is an isometric view of the filter element ofFIG. 1 shown alone according to an embodiment of the present invention with the isometric view shown in cross-section. -
FIG. 3 is a similar, but isometric cross-section view as that ofFIG. 2 , but with the filter media ring removed. -
FIG. 4 is a cross-section view similar toFIG. 3 , but not from an isometric view, but from a side elevation view. -
FIG. 5 is an enlarged cross-section of part of the filter element to better illustrate the snorkel and the bleed chamber in pathways therethrough. -
FIG. 6 is an isometric cross-section view of a filter element according to another embodiment of the present invention. - While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
- A first embodiment is illustrated in
FIGS. 1-5 , showing afilter element 10 installed in ahousing 12. As illustrated and described herein, thefilter element 10 includes asnorkel 14 that facilitates bleeding of much of the air that is trapped in the housing during initial installation or replacement of the filter element. Thesnorkel 14 facilitates bleeding of air out of the housing and back to a fuel tank or otherwise outside thehousing 12. - The
housing 12 includes afuel inlet 16 and afuel outlet 18 with afuel flow path 20 for delivering fuel flow to an engine. Thefuel flow path 20 is illustrated schematically extending from theinlet 16 to the outlet and through the filter element for filtration of contaminants. Astandpipe 22 extends from abase 24 of thehousing 12 toward the top end of the housing. To facilitate installation and removal, thehousing 12 may comprise acontainer bottom 26 including thebase 24 as well as a screw-oncover 28 that threadably mounts and seals the top side of thecontainer bottom 26. In this manner, thecover 28 can be removed to facilitate removal and replacement of thefilter element 10. - The
fuel flow path 20 extends through thestandpipe 22 along afirst passage 30 defined in the standpipe. The standpipe further defines a second air bleed passage 32 that is defined separately and isolated from thefirst passage 30. Thefirst passage 30 includes aninlet port 34 toward a top end of the standpipe along a smaller diameter section of the standpipe while the second air bleed passage includes a separate isolatedinlet port 36 connected to the second air bleed passage 32 along a conical section that joins the smaller diameter section of the standpipe to a larger diameter section of the standpipe at the bottom end. Thestandpipe 22 facilitates and provides isolation structure between the first passage and the second air bleed passage so that filter fuel passing through the filter element is directed toward the engine while the air or unfiltered fuel carried along this path may be recirculated back to the tank or otherwise exits thehousing 12. - As illustrated, the
filter element 10 is disposed in thehousing 12 and over thestandpipe 22. The filter element includes atop end cap 38 and abottom end cap 40 that is disposed below the top end cap. Thebottom end cap 40 defines acentral opening 42 that receives the standpipe therethrough. The tubular ring of filter media 44 (which may be a cylindrical tube of pleated filter media) extends between the top andbottom end caps open volume 46 that receives the standpipe and provides for flow along theflow path 20 through the filter media. As the flow path passes through thefilter media 44, the filter media filters the fuel flowing along that flow path. Thebleed chamber 48 is provided proximate thebottom end cap 40 and is preferably defined in part, by the bottom end cap. Thebleed chamber 48 is therefore in fluid communication with the second bleed passage 32 ofstandpipe 22. Thesnorkel 14 is in fluid communication with thisbleed chamber 48 and extends along the outside of thefilter media 44 with avent opening 50 closer to the top end cap then the bottom end cap and preferably very close to the top end cap to facilitate removal of most of the air from the housing during installation or replacement of thefilter element 10 and, thereby, maximize the filtration capacity usage of the filter. - The
filter element 10 also preferably includes first and secondannular seals bleed chamber 48 is defined at least in part between theseannular seals - Additionally, the filter element preferably includes a
support core 56 that extends between bottom and top end caps. The support core can radially support the filter media against the flow and flow restriction caused by the media as flow passes through it. - As illustrated, the
first seal 52 is of smaller diameter than thesecond seal 54, with thefirst seal 52 mounted to the support core 56 (on an inward flange thereof) and thesecond seal 54 mounted to thebottom end cap 40. The first smallerannular seal 52 can seal on the smaller diameter section of the standpipe while the second largerannular seal 54 can seal on the larger diameter section of the standpipe. With these seals, the bleed chamber is along the outside of the standpipe. - The bottom end cap may be constructed of one or more component parts. This
bottom end cap 40 embodiment includes anannular channel 58 that facilitates potting of thefilter media 44 to the bottom end to sealingly bond the bottom end of the filter media. Theannular channel 58 extends along a bottom 60 with aring name member 62 spaced from the bottom 60 and providing a raised floor for thebottom end cap 40. As illustrated, thebleed chamber 48 extends through afirst aperture 64 in the support core (a plurality ofsuch vent apertures 64 may be provided) and through a vent aperture 76 (seeFIG. 5 ) in theinner wall 70 of the bottom end cap into anannular space 66 defined between the bottom 60 and thering member 62. Thering member 62 may be molded to include an integrally formedspout 68 extending upwardly to which thesnorkel 14 is mounted. - Further, the bottom end cap may also include an inner
annular wall 70 and an outerannular wall 72. Further, a thirdannular seal 74 may be provided to seal between thesupport core 56 and the bottom end cap (particularly the inner annular wall of the bottom end cap). Afurther vent orifice 76 is provided in the innerannular wall 70 to communicate thebleed chamber 48 into theannular space 66.Spacer element 78, which may be either integral with the bottom 60 or the ring member 62 (shown as integral in this embodiment with bottom 60) may be provided between the bottom 60 and thering member 62 provide for spacing.Spacer elements 78 may comprise spared tabs angularly spaced about the central axis and opening so that fluid can pass radially without restriction past the spacer elements. Further, snap retainers may be provided on at least one of the outsideannular wall 72 and/or the insideannular wall 70, which provide for snap in retention of thering member 62 with abutment ofspacing elements 78. - Potting compounds such as Plastisol, urethanes, or other adhesive may be used to sealingly bond the opposed axial ends of the tubular ring of
filter media 44 to the respective top and bottom end caps 38, 40. An advantage of using potting compound in this embodiment is that it may seal the cracks between thering member 62 and the inner and outerannular walls bottom end cap 40. - The tubular ring of
filter media 44 may be a generally cylindrical pleat pack having pleats. In this embodiment, there is featured the provision of installing thesnorkel 14, which may comprise an elongated, vertically extendingtube 82, mounted onspout 68 in a telescopic interfitting manner. Further, the snorkel and tube may extend in a longitudinal gap between adjacent pleats of the tubular ring ofmedia 44. Thus,snorkel tube 82 is along the outside of the pleated filter pack, but yet contained radially inward of the outer peripheries of the top and bottom end caps. Further, the top end cap may be a solid structure and no opening need be provided therein, and the second end cap may define a restriction orifice, which may be integral with thespout 68 structure that serves to limit the flow rate through the snorkel to allow for venting of air, but not causing excess return flow of fuel to tank. - With this arrangement and according to various embodiments, a method of filtering fuel is provided while venting air through a filter element that is installed in a housing comprising filtering fluid through filter media of the filter element; venting air trapped in the housing through a snorkel integrally part of the filter element; and extending the snorkel along the outside periphery of the filter media. Further, a bleed chamber may be sealed around the standpipe that extends into the filter element and underneath the tubular ring of filter media with the bleed chamber being formed into the filter element. In this manner, vented air can be communicated into the seal bleed chamber in sealed isolation in relation to the filtered fluid.
- Another embodiment, similar to the first, is shown in
FIG. 6 showing afilter element 100 that is in all aspects similar to filterelement 10 with some distinctions pointed out herein. As such, prior structures and functions above will not be repeated, but can apply to this embodiment.Filter element 100 includes a bottom end cap 102 with a horizontal pipe and/orpassage 104 extending through the outerannular wall 106. Thus, thebleed chamber 108 provided on the inner annular wall of bottom end cap 102 extends through the horizontal pipe orpassage 104 to the outer periphery of the bottom end cap. Bleedchamber 108, thereby, also extends underneath the tubular ring of filter media. Potting compound may be also employed in the bottom end cap and annular channel (above the passage 104), thereof, to facilitate potting. In this embodiment, thesnorkel 110 is provided along the outside of the bottom end cap and extends to the outside peripheries of the top and bottom end caps. Thesnorkel 110 includes asnorkel connection 112 plugged into the horizontal pipe, orpassage 104, with a vertically extendingsnorkel tube 114 extending vertically upward and all the way to the top end cap to thereby provide for air bleed through the snorkel and into the bleed chamber. - All references, including publications, patent applications, and patents cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
